When putting new ABS\PVC in the tank as caves, is just washing with water & brush only that needs to be done? And yes I have read all the debate about putting ABS in fish tank being safe or not.
Listen online: you can wash it, then add it to your tank. But keep in mind that you have NO IDEA where that pipe was before or what was "spilled" on to, or in it. Bleaching it will kill all those "hitchhikers"
PVC is naturally safe? must be from all the precautions they use when theyre mining it. you know? from those big PVC mines? theyre in Virginia arent they? where all those workers were trapped. mining a big vein of PVC.
or do they farm PVC in Nebraska? i never can remember....
i never bleach anything in my aquarium. im too paranoid that i wont get it all rinsed off.
